Elisa's mom teaches at a preschool. There is 1 teacher for every 12 students at the preschool. There are 276 students at the preschool. How do you set up equivalent ratios to find the number of teachers at the preschool?

23 teachers needed

Explanation:

the ratio that you will need is: teacher to student.

Let $x$ = number of teachers needed

$\frac{1}{12}$ = $\frac{x}{276}$

cross multiply; 1(276) = 12($x$)

divide both sides by 12

$x$ - 23 teachers needed
